FIELD

The present disclosure belongs to the technical field of clothingtreatment, and specifically provides a clothing treatment apparatus.

BACKGROUND

A clothing treatment apparatus is an apparatus capable of washing,drying, sterilizing and/or deodorizing clothing. With the continuousimprovement of production level and ongoing growth of users' needs,users have also raised higher and higher requirements on the clothingtreatment apparatus.

In the prior art, taking a washing machine as an example, the clothingis generally washed by water. The washing process is accompanied bymechanical rotation, so that stains on the clothing are washed away.However, this washing method has a limitation in that if a large amountof water is injected into a washing drum at the beginning, the stains ona surface of the clothing will directly enter a lining of the clothingin a state where a washing liquid is not completely dissolved, so thatmore time, water amount, washing liquid and mechanical action arerequired for washing the clothing clean in the subsequent washingprocess, thus resulting in a poor washing effect. In existing clothingtreatment apparatuses, other functions are often added on the basis of awashing machine, such as adding a drying function to become awashing-drying integrated machine, etc. Such an improvement does notsignificantly improve the washing effect of the washing machine.Moreover, current washing machines still cannot achieve in-depthtreatment of clothing made of special materials, such as cashmere, wooland other materials. If the traditional washing by water is used, it ishighly possible that fiber structures of the clothing will be damaged,which has caused a very big limitation on an applicable range of theclothing of the washing machine.

Accordingly, there is a need for a new clothing treatment apparatus inthe art to solve the above problems.

SUMMARY

In order to solve the above problems in the prior art, that is, to solvethe problems of poor washing effect and very limited applicable range ofclothing of existing clothing treatment apparatuses with a washingfunction, the present disclosure provides a clothing treatmentapparatus.

First Technical Solution

As shown in FIG. 1, the clothing treatment apparatus of the presentdisclosure includes a clothing treatment drum, a water supply valve 1, adispensing device 2, a water-containing member, an atomization generator3, and a one-way check mechanism. The dispensing device 2 includes awater delivery channel 21, the water supply valve 1 is connected to awater inlet end of the water delivery channel 21, and a water outlet endof the water delivery channel 21 is connected to the atomizationgenerator 3 through the water-containing member. An outlet of theatomization generator 3 is arranged facing an inner cavity of theclothing treatment drum. The one-way check mechanism is connected withthe water delivery channel 21 and the water-containing memberrespectively, and the one-way check mechanism is arranged to be isolatedfrom the atmosphere when the water supply valve 1 is opened and tocommunicate with the atmosphere when the water supply valve 1 is closed.The water-containing member may be a water tank, or a water box, or asink on the clothing treatment apparatus. Those skilled in the art mayflexibly set the specific structure of the water-containing member inpractical applications, as long as the water-containing member can storeand accommodate water. The atomization generator 3 may be an ultrasonicatomization generator or a compressed atomization generator. Thoseskilled in the art may flexibly set the specific structure of theatomization generator 3 in practical applications, as long as theatomization generator 3 can convert the water in the water deliverychannel 21 and the water-containing member into atomized water dropletswhen the one-way check structure communicates with the atmosphere so asto perform atomized air washing of the clothing. In addition, a combinedstructure of a one-way check valve 7 and pipelines may be used as theone-way check structure, in which the one-way check valve 7 may be theone-way check valve in the patent No. 201721853840.8. The principle ofthe one-way check valve 7 belongs to the prior art, so it will not bedescribed in detail herein. Of course, in the present disclosure, othercombined structures of a one-way check structure and pipelines may alsobe used. For example, the one-way check structure includes a cylinder, amovable block arranged in the cylinder, and a spring connected betweenthe cylinder and the movable block. The movable block divides aninternal cavity of the cylinder into two parts. A top part of thecylinder is provided with an air inlet, a bottom part of the cylinder isprovided with a water inlet, and a middle part of the cylinder isprovided with an outlet. The spring allows the movable block to movebetween a top limit position, a middle position and a bottom limitposition. When the spring is in a natural state, it enables the movableblock to be maintained at the bottom limit position. At this time, theair inlet communicates with the outlet, and the water inlet is isolatedfrom the outlet by the movable block, so as to realize the communicationbetween the one-way check structure and the atmosphere. When waterinflows from the water inlet, the water pressure moves the movable blockto the top limit position against the force of the spring, so that thewater inlet communicates with the outlet, and that the air inlet isisolated from the outlet by the movable block. Therefore, the one-waycheck structure allows water to pass through and be isolated from theatmosphere. It should be noted that the above-mentioned top part andbottom part are defined relative to the cylinder, and they do notconstitute restrictions to the specific direction of arranging theone-way check structure. Alternatively, the one-way check structure mayalso be a combined structure of a plug and pipelines. Specifically, thewater delivery channel 21 and the water-containing member are connectedby a connection pipe, an opening is provided at the highest point of theconnection pipe, and a plug is provided at the opening. When waterinflows from the water supply valve 1, the opening is closed by theplug, and when the water supply valve 1 is closed, the plug is removedand the opening communicates with the atmosphere, so that the water inthe water delivery channel 21 and the water-containing member is sprayedfrom the outlet of the atomization generator 3. Those skilled in the artmay flexibly set the specific structure of the one-way check structurein practical applications, as long as the one-way check structure can beisolated from the atmosphere when the water supply valve 1 is opened andcan communicate with the atmosphere when the water supply valve 1 isclosed.

It should be noted that by using the one-way check structure, thepresent disclosure enables the atomization generator 3 to smoothlygenerate atomized water droplets. This is because when the water supplyvalve 1 is always open, it is very difficult for the atomizationgenerator 3 to form atomized water droplets under the action of waterpressure. Therefore, the water supply valve 1 can be opened toaccumulate water in the water delivery channel 21 and thewater-containing member, and then the water supply valve 1 can beclosed. At this time, the water in the water delivery channel 21 and thewater-containing member can be sprayed onto the clothing in the form ofatomized water droplets from the atomization generator 3 according tothe principle of atmospheric communication, so as to ensure that theatomization generator 3 can perform atomized air washing of theclothing.

In addition, it should also be noted that the clothing treatmentapparatus of the present disclosure may be a drum washing machine, apulsator washing machine, a washing-drying integrated machine, aclothing care machine, etc., and those skilled in the art may flexiblyset the application objects of the technical solutions of the presentdisclosure. Such adjustments and changes to the application objects donot deviate from the principle of the present disclosure, and should bedefined within the scope of protection of the present disclosure. Thetechnical solutions of the present disclosure will be further explainedbelow in conjunction with a drum washing machine.

Specifically, as shown in FIGS. 1 and 2, the drum washing machine of thepresent disclosure includes a cabinet, a drum 4 arranged in the cabinet,and a window gasket 5 connected between an outer cylinder of the drum 4and the cabinet. The atomization generator 3 is preferably arranged onthe window gasket 5, and an outlet of the atomization generator 3 isobliquely arranged facing an inner cavity of the drum 4 (of course,other directions of arrangement are also possible). Alternatively, theatomization generator 3 may also be provided on the outer cylinder ofthe drum 4, as long as it can spray atomized water droplets onto theclothing in an inner cylinder of the drum 4 to perform atomized airwashing. In addition, the drum washing machine also includes adispensing device 2 arranged on the cabinet. The dispensing device 2includes a clothing treatment agent dispensing cavity and a water boxarranged on a top of the clothing treatment agent dispensing cavity. Thewater delivery channel 21 is formed in the water box. A water inlet endof the water delivery channel 21 is connected to the water supply valve1 arranged outside of the dispensing device 2, and a water outlet end ofthe water delivery channel 21 is connected to a water tank 6 through apipeline. The water tank 6 is connected to the atomization generator 3through a pipeline, and the water tank 6 has a function of accumulatingwater. The one-way check valve 7 is arranged outside of the waterdelivery channel 21 and the water tank 6, the one-way check valve 7 isconnected to the water delivery channel 21 through a first pipeline 8,and the one-way check valve 7 is also connected to the water tank 6through a second pipeline 9 (this part of the structure is not shown inFIG. 2).

Preferably, the position where the one-way check valve 7 is arranged isat a different height from the position where the outlet of theatomization generator 3 is arranged, that is, when the one-way checkvalve 7 communicates with the atmosphere, a certain liquid leveldifference can be formed between the one-way check valve 7 and theoutlet of the atomization generator 3, so that the water accumulated inthe water delivery channel 21 and the water tank 6 can be sprayed ontothe clothing more easily in the form of atomized water droplets throughthe atomization generator 3. Since the position where the dispensingdevice 2 is arranged is generally higher than the position where thedrum 4 is arranged in the drum washing machine, it is more preferable toset the position where the one-way check valve 7 is arranged to behigher than the position where the outlet of the atomization generator 3is arranged, thereby making full use of the original structure of thedrum washing machine.

Second Technical Solution

As shown in FIG. 3, the clothing treatment apparatus of the presentdisclosure includes a clothing treatment drum, a water supply valve 1, adispensing device 2, a water-containing member, and an atomizationgenerator 3. The dispensing device 2 includes a water delivery channel21, the water supply valve 1 is connected to a water inlet end of thewater-containing member through the water delivery channel 21, a wateroutlet end of the water-containing member is connected to theatomization generator 3 through a first pipeline 9, and the water outletend of the water-containing member is also connected to the clothingtreatment drum through a second pipeline 10. An outlet of theatomization generator 3 is arranged facing an inner cavity of theclothing treatment drum. The water delivery channel 21 and/or thewater-containing member are provided with a one-way check mechanism, andthe one-way check mechanism is arranged to be isolated from theatmosphere when the water supply valve 1 is opened and to communicatewith the atmosphere when the water supply valve 1 is closed. Thewater-containing member may be a water tank, or a water box, or a sinkon the clothing treatment apparatus. Those skilled in the art mayflexibly set the specific structure of the water-containing member inpractical applications, as long as the water-containing member can storeand accommodate water. The atomization generator 3 may be an ultrasonicatomization generator or a compressed atomization generator. Thoseskilled in the art may flexibly set the specific structure of theatomization generator 3 in practical applications, as long as theatomization generator 3 can convert the water in the water-containingmember into atomized water droplets when the one-way check structurecommunicates with the atmosphere so as to perform atomized air washingof the clothing. In addition, a one-way check valve 8 may be used as theone-way check structure, such as the one-way check valve 8 in the patentNo. 201721853840.8. The principle of the one-way check valve 8 belongsto the prior art, so it will not be described in detail herein. Ofcourse, in the present disclosure, other one-way check structures mayalso be used. For example, the one-way check structure includes acylinder, a movable block arranged in the cylinder, and a springconnected between the cylinder and the movable block. The movable blockdivides an internal cavity of the cylinder into two parts. A top part ofthe cylinder is provided with an air inlet, a bottom part of thecylinder is provided with a water inlet, and a middle part of thecylinder is provided with an outlet. The spring allows the movable blockto move between a top limit position, a middle position and a bottomlimit position. When the spring is in a natural state, it enables themovable block to be maintained at the bottom limit position. At thistime, the air inlet communicates with the outlet, and the water inlet isisolated from the outlet by the movable block, so as to realize thecommunication between the one-way check structure and the atmosphere.When water inflows from the water inlet, the water pressure moves themovable block to the top limit position against the force of the spring,so that the water inlet communicates with the outlet, and that the airinlet is isolated from the outlet by the movable block. Therefore, theone-way check structure allows water to pass through and be isolatedfrom the atmosphere. It should be noted that the above-mentioned toppart and bottom part are defined relative to the cylinder, and they donot constitute restrictions to the specific direction and specificposition of arranging the one-way check structure. Alternatively, theone-way check structure may also be a plug structure. Specifically, anopening is provided at the highest point of the water delivery channel21 and/or the water-containing member, and a plug is provided at theopening. When water inflows from the water supply valve 1, the openingis closed by the plug, and when the water supply valve 1 is closed, theplug is removed and the opening communicates with the atmosphere, sothat the water in the water-containing member is sprayed from the outletof the atomization generator 3. Those skilled in the art may flexiblyset the specific structure of the one-way check structure in practicalapplications, as long as the one-way check structure can be isolatedfrom the atmosphere when the water supply valve 1 is opened and cancommunicate with the atmosphere when the water supply valve 1 is closed.Moreover, it is possible to arrange the one-way check structure only onthe water delivery channel 21. With this structure, if the one-way checkstructure communicates with the atmosphere, the water in the waterdelivery channel 21 and the water in the water-containing member willboth flow into the interior of the clothing treatment drum through theatomization generator 3. Of course, the water delivery channel 21 andthe water-containing member may also be provided with a one-way checkstructure respectively, so that when the one-way check structurecommunicates with the atmosphere, the water in the water deliverychannel 21 and the water in the water-containing member will both flowinto the interior of the clothing treatment drum through the atomizationgenerator 3. Alternatively, it is also possible to arrange the one-waycheck structure only on the water-containing member. In this case, whenthe one-way check structure communicates with the atmosphere, at leastthe water in the water-containing member can flow into the interior ofthe clothing treatment drum through the atomization generator 3. Thoseskilled in the art may flexibly set the arrangement position anddistribution of the one-way check structure in practical applications,as long as it can be ensured that at least the water in thewater-containing member can flow into the interior of the clothingtreatment drum through the atomization generator 3 to realize theatomized air washing of the clothing. In the present disclosure, thefirst pipeline 9 and the second pipeline 10 may be connected to thewater delivery channel 21 through the same water outlet end of the waterdelivery channel 21, or they may also be connected to the water deliverychannel 21 through different water outlet ends of the water deliverychannel 21 respectively. Such changes to the structure do not deviatefrom the technical solutions of the present disclosure, and should bedefined within the scope of protection of the present disclosure.

It should be noted that by using the one-way check structure, thepresent disclosure enables the atomization generator 3 to smoothlygenerate atomized water droplets. This is because when the water supplyvalve 1 is always open, it is very difficult for the atomizationgenerator 3 to form atomized water droplets under the action of waterpressure. Therefore, the water supply valve 1 can be opened toaccumulate water in the water delivery channel 21 and thewater-containing member, and then the water supply valve 1 can be closed(the second pipeline 10 is selectively closed at this time). At thistime, at least a part of the water in the water-containing member can besprayed onto the clothing in the form of atomized water droplets fromthe atomization generator 3 according to the principle of atmosphericcommunication, so as to ensure that the atomization generator 3 canperform atomized air washing of the clothing. If it is required toinject a large amount of water into the clothing treatment drum, theatomization generator 3 is closed at this time so as to keep the watersupply valve 1 always open and ensure that the second pipeline 10 is ina communicated state, thereby achieving continuous water injection intothe clothing treatment drum. The second pipeline 10 can be directlyconnected to a water injection port or sprinkling structure on theclothing treatment drum.

In addition, it should also be noted that the clothing treatmentapparatus of the present disclosure may be a drum washing machine, apulsator washing machine, a washing-drying integrated machine, aclothing care machine, etc., and those skilled in the art may flexiblyset the application objects of the technical solutions of the presentdisclosure. Such adjustments and changes to the application objects donot deviate from the principle of the present disclosure, and should bedefined within the scope of protection of the present disclosure. Thetechnical solutions of the present disclosure will be further explainedbelow in conjunction with a drum washing machine.

Specifically, as shown in FIG. 4, the drum washing machine of thepresent disclosure includes a cabinet, a drum 4 arranged in the cabinet,and a window gasket 5 connected between an outer cylinder of the drum 4and the cabinet. The atomization generator 3 is preferably arranged onthe window gasket 5, and an outlet of the atomization generator 3 isobliquely arranged facing an inner cavity of the drum 4 (of course,other directions of arrangement are also possible). Alternatively, theatomization generator 3 may also be provided on the outer cylinder ofthe drum 4, as long as it can spray atomized water droplets onto theclothing in an inner cylinder of the drum 4 to perform atomized airwashing. A sprinkling head 7 is provided on the drum 4 or on the windowgasket 5, and an outlet of the sprinkling head 7 is also arranged facingthe inner cavity of the drum 4. The sprinkling head 7 is mainlyconfigured to sprinkle water into the drum 4. A control valve may beselectively installed on the second pipeline 10, and the control valvecan control on and off of the second pipeline 10. In addition, the drumwashing machine also includes a dispensing device 2 arranged on thecabinet. The dispensing device 2 includes a clothing treatment agentdispensing cavity and a water box arranged on a top of the clothingtreatment agent dispensing cavity. The water delivery channel 21 isformed in the water box. A water inlet end of the water delivery channel21 is connected to the water supply valve 1 arranged outside of thedispensing device 2, and a water outlet end of the water deliverychannel 21 is connected to a water tank 6 through a pipeline. The watertank 6 is connected to the atomization generator 3 through the firstpipeline 9, and is connected to the sprinkling head 7 through the secondpipeline 10. The water tank 6 has a function of accumulating water. Theone-way check valve 8 is arranged on the water delivery channel 21. Forexample, the one-way check valve 8 may be arranged close to the waterinlet end of the water delivery channel 21. Of course, the one-way checkvalve 8 may also be arranged at other positions of the water deliverychannel 21. Those skilled in the art may flexibly set the position wherethe one-way check valve 8 is arranged in the water delivery channel 21in practical applications. Such adjustments and changes to thearrangement position of the one-way check valve 8 do not constitutelimitations to the present disclosure, and should be defined within thescope of protection of the present disclosure.

Preferably, the position where the one-way check valve 8 is arranged isat a different height from the position where the outlet of theatomization generator 3 is arranged, that is, when the one-way checkvalve 8 communicates with the atmosphere, a certain liquid leveldifference can be formed between the one-way check valve 8 and theoutlet of the atomization generator 3, so that the water accumulated inthe water delivery channel 21 and the water tank 6 can be sprayed ontothe clothing more easily in the form of atomized water droplets throughthe atomization generator 3. Since the position where the dispensingdevice 2 is arranged is generally higher than the position where thedrum 4 is arranged in the drum washing machine, it is more preferable toset the position where the one-way check valve 8 is arranged to behigher than the position where the outlet of the atomization generator 3is arranged, thereby making full use of the original structure of thedrum washing machine.

Third Technical Solution

As shown in FIG. 5, the clothing treatment apparatus of the presentdisclosure includes a clothing treatment drum, a water supply valve 1, adispensing device 2, a water-containing member, and an atomizationgenerator 3. The dispensing device 2 includes a water delivery channel21, the water supply valve 1 is connected to a water inlet end of thewater delivery channel 21, and a water outlet end of the water deliverychannel 21 is connected to the atomization generator 3 through thewater-containing member. An outlet of the atomization generator 3 isarranged facing an inner cavity of the clothing treatment drum. Thewater delivery channel 21 and/or the water-containing member areprovided with a one-way check mechanism, and the one-way check mechanismis arranged to be isolated from the atmosphere when the water supplyvalve 1 is opened and to communicate with the atmosphere when the watersupply valve 1 is closed. The water-containing member may be a watertank, or a water box, or a sink on the clothing treatment apparatus.Those skilled in the art may flexibly set the specific structure of thewater-containing member in practical applications, as long as thewater-containing member can store and accommodate water. The atomizationgenerator 3 may be an ultrasonic atomization generator or a compressedatomization generator. Those skilled in the art may flexibly set thespecific structure of the atomization generator 3 in practicalapplications, as long as the atomization generator 3 can convert thewater in the water-containing member into atomized water droplets whenthe one-way check structure communicates with the atmosphere so as toperform atomized air washing of the clothing. In addition, a one-waycheck valve 7 may be used as the one-way check structure, such as theone-way check valve 7 in the patent No. 201721853840.8. The principle ofthe one-way check valve 7 belongs to the prior art, so it will not bedescribed in detail herein. Of course, in the present disclosure, otherone-way check structures may also be used. For example, the one-waycheck structure includes a cylinder, a movable block arranged in thecylinder, and a spring connected between the cylinder and the movableblock. The movable block divides an internal cavity of the cylinder intotwo parts. A top part of the cylinder is provided with an air inlet, abottom part of the cylinder is provided with a water inlet, and a middlepart of the cylinder is provided with an outlet. The spring allows themovable block to move between a top limit position, a middle positionand a bottom limit position. When the spring is in a natural state, itenables the movable block to be maintained at the bottom limit position.At this time, the air inlet communicates with the outlet, and the waterinlet is isolated from the outlet by the movable block, so as to realizethe communication between the one-way check structure and theatmosphere. When water inflows from the water inlet, the water pressuremoves the movable block to the top limit position against the force ofthe spring, so that the water inlet communicates with the outlet, andthat the air inlet is isolated from the outlet by the movable block.Therefore, the one-way check structure allows water to pass through andbe isolated from the atmosphere. It should be noted that theabove-mentioned top part and bottom part are defined relative to thecylinder, and they do not constitute restrictions to the specificdirection and specific position of arranging the one-way checkstructure. Alternatively, the one-way check structure may also be a plugstructure. Specifically, an opening is provided at the highest point ofthe water delivery channel 21 and/or the water-containing member, and aplug is provided at the opening. When water inflows from the watersupply valve 1, the opening is closed by the plug, and when the watersupply valve 1 is closed, the plug is removed and the openingcommunicates with the atmosphere, so that the water in thewater-containing member is sprayed from the outlet of the atomizationgenerator 3. Those skilled in the art may flexibly set the specificstructure of the one-way check structure in practical applications, aslong as the one-way check structure can be isolated from the atmospherewhen the water supply valve 1 is opened and can communicate with theatmosphere when the water supply valve 1 is closed. Moreover, it ispossible to arrange the one-way check structure only on the waterdelivery channel 21. With this structure, if the one-way check structurecommunicates with the atmosphere, the water in the water deliverychannel 21 and the water in the water-containing member will both flowinto the interior of the clothing treatment drum through the atomizationgenerator 3. Of course, the water delivery channel 21 and thewater-containing member may also be provided with a one-way checkstructure respectively, so that when the one-way check structurecommunicates with the atmosphere, the water in the water deliverychannel 21 and the water in the water-containing member will both flowinto the interior of the clothing treatment drum through the atomizationgenerator 3. Alternatively, it is also possible to arrange the one-waycheck structure only on the water-containing member. In this case, whenthe one-way check structure communicates with the atmosphere, at leastthe water in the water-containing member can flow into the interior ofthe clothing treatment drum through the atomization generator 3. Thoseskilled in the art may flexibly set the arrangement position anddistribution of the one-way check structure in practical applications,as long as it can be ensured that at least the water in thewater-containing member can flow into the interior of the clothingtreatment drum through the atomization generator 3 to realize theatomized air washing of the clothing.

It should be noted that by using the one-way check structure, thepresent disclosure enables the atomization generator 3 to smoothlygenerate atomized water droplets. This is because when the water supplyvalve 1 is always open, it is very difficult for the atomizationgenerator 3 to form atomized water droplets under the action of waterpressure. Therefore, the water supply valve 1 can be opened toaccumulate water in the water delivery channel 21 and thewater-containing member, and then the water supply valve 1 can beclosed. At this time, at least the water in the water-containing membercan be sprayed onto the clothing in the form of atomized water dropletsfrom the atomization generator 3 according to the principle ofatmospheric communication, so as to ensure that the atomizationgenerator 3 can perform atomized air washing of the clothing.

In addition, it should also be noted that the clothing treatmentapparatus of the present disclosure may be a drum washing machine, apulsator washing machine, a washing-drying integrated machine, aclothing care machine, etc., and those skilled in the art may flexiblyset the application objects of the technical solutions of the presentdisclosure. Such adjustments and changes to the application objects donot deviate from the principle of the present disclosure, and should bedefined within the scope of protection of the present disclosure. Thetechnical solutions of the present disclosure will be further explainedbelow in conjunction with a drum washing machine.

Specifically, as shown in FIG. 6, the drum washing machine of thepresent disclosure includes a cabinet, a drum 4 arranged in the cabinet,and a window gasket 5 connected between an outer cylinder of the drum 4and the cabinet. The atomization generator 3 is preferably arranged onthe window gasket 5, and an outlet of the atomization generator 3 isobliquely arranged facing an inner cavity of the drum 4 (of course,other directions of arrangement are also possible). Alternatively, theatomization generator 3 may also be provided on the outer cylinder ofthe drum 4, as long as it can spray atomized water droplets onto theclothing in an inner cylinder of the drum 4 to perform atomized airwashing. In addition, the drum washing machine also includes adispensing device 2 arranged on the cabinet. The dispensing device 2includes a clothing treatment agent dispensing cavity and a water boxarranged on a top of the clothing treatment agent dispensing cavity. Thewater delivery channel 21 is formed in the water box. A water inlet endof the water delivery channel 21 is connected to the water supply valve1 arranged outside of the dispensing device 2, and a water outlet end ofthe water delivery channel 21 is connected to a water tank 6 through apipeline. The water tank 6 is connected to the atomization generator 3through a pipeline, and the water tank 6 has a function of accumulatingwater. The one-way check valve 7 is arranged on the water deliverychannel 21. For example, the one-way check valve 7 may be arranged closeto the water inlet end of the water delivery channel 21. Of course, theone-way check valve 7 may also be arranged at other positions of thewater delivery channel 21. Those skilled in the art may flexibly set theposition where the one-way check valve 7 is arranged in the waterdelivery channel 21 in practical applications. Such adjustments andchanges to the arrangement position of the one-way check valve 7 do notconstitute limitations to the present disclosure, and should be definedwithin the scope of protection of the present disclosure.

Preferably, the position where the one-way check valve 7 is arranged isat a different height from the position where the outlet of theatomization generator 3 is arranged, that is, when the one-way checkvalve 7 communicates with the atmosphere, a certain liquid leveldifference can be formed between the one-way check valve 7 and theoutlet of the atomization generator 3, so that the water accumulated inthe water delivery channel 21 and the water tank 6 can be sprayed ontothe clothing more easily in the form of atomized water droplets throughthe atomization generator 3. Since the position where the dispensingdevice 2 is arranged is generally higher than the position where thedrum 4 is arranged in the drum washing machine, it is more preferable toset the position where the one-way check valve 7 is arranged to behigher than the position where the outlet of the atomization generator 3is arranged, thereby making full use of the original structure of thedrum washing machine.

Fourth Technical Solution

As shown in FIG. 7, the clothing treatment apparatus of the presentdisclosure includes a clothing treatment drum, a water supply valve 1, adispensing device 2, and an atomization generator 3. The dispensingdevice 2 includes a water delivery channel 21, the water supply valve 1is connected to a water inlet end of the water delivery channel 21, awater outlet end of the water delivery channel 21 is connected to theatomization generator 3 through a first pipeline 4, and the water outletend of the water delivery channel 21 is also connected to a secondpipeline 5. An outlet of the second pipeline 5 is arranged facing aninner cavity of the clothing treatment drum, an outlet of theatomization generator 3 is arranged facing an inner cavity of theclothing treatment drum, and the second pipeline 5 is arranged to beable to communicate with the atmosphere. The second pipeline 5 may bedirectly connected to the clothing treatment drum, and the outlet of thesecond pipeline 5 may also be arranged above the clothing treatmentdrum. Those skilled in the art may flexibly set the ways of arrangingand connecting the second pipeline 5 in practical applications, as longas water can be injected into the clothing treatment drum through thesecond pipeline 5. In addition, the technical solution of the presentdisclosure may also be applied to a clothing treatment apparatus with amulti-drum structure, such as a dual-drum washing machine, whichincludes a first drum and a second drum. The outlet of the atomizationgenerator 3 is arranged facing an inner cavity of the first drum, andthe outlet of the second pipeline 5 is arranged facing an inner cavityof the second drum, so that water can be injected into the first drumand the second drum through the same water supply valve 1. Atomizedwater injection is implemented in the first drum (in which other waterinjection structures may also be included), and direct water injectionis implemented in the second drum (including water injection bysprinkling, etc.). Those skilled in the art may flexibly set theapplication scenes of the present disclosure in practical applications,as long as at least the atomized air washing of the clothing can berealized. The atomization generator 3 may be an ultrasonic atomizationgenerator or a compressed atomization generator. Those skilled in theart may flexibly set the specific structure of the atomization generator3 in practical applications, as long as the atomization generator 3 canconvert the water in the water delivery channel 21 and the firstpipeline 4 into atomized water droplets when the second pipeline 5communicates with the atmosphere so as to perform atomized air washingof the clothing. It should be noted that the second pipeline 5 of thepresent disclosure may be a structure that is always in communicationwith the atmosphere. For example, the outlet of the second pipeline 5 isarranged above the clothing treatment drum, and the outlet of the secondpipeline 5 is arranged facing the inner cavity of the clothing treatmentdrum. Of course, the second pipeline 5 may also be a structure that canselectively communicate with the atmosphere. The technical solution ofthe present disclosure will be further explained below in conjunctionwith this structure.

Preferably, the second pipeline 5 includes a pipeline body and a one-waycheck structure provided on the pipeline body, and the one-way checkstructure is arranged to be isolated from the atmosphere when the watersupply valve 1 is opened and to communicate with the atmosphere when thewater supply valve 1 is closed. A one-way check valve may be used as theone-way check structure, such as the one-way check valve in the patentNo. 201721853840.8. The principle of the one-way check valve belongs tothe prior art, so it will not be described in detail herein. Of course,in the present disclosure, other one-way check structures may also beused. For example, the one-way check structure includes a cylinder, amovable block arranged in the cylinder, and a spring connected betweenthe cylinder and the movable block. The movable block divides aninternal cavity of the cylinder into two parts. A top part of thecylinder is provided with an air inlet, a bottom part of the cylinder isprovided with a water inlet, and a middle part of the cylinder isprovided with an outlet. The spring allows the movable block to movebetween a top limit position, a middle position and a bottom limitposition. When the spring is in a natural state, it enables the movableblock to be maintained at the bottom limit position. At this time, theair inlet communicates with the outlet, and the water inlet is isolatedfrom the outlet by the movable block, so as to realize the communicationbetween the one-way check structure and the atmosphere. When waterinflows from the water inlet, the water pressure moves the movable blockto the top limit position against the force of the spring, so that thewater inlet communicates with the outlet, and that the air inlet isisolated from the outlet by the movable block. Therefore, the one-waycheck structure allows water to pass through and be isolated from theatmosphere. It should be noted that the above-mentioned top part andbottom part are defined relative to the cylinder, and they do notconstitute restrictions to the specific direction and specific positionof arranging the one-way check structure. Alternatively, the one-waycheck structure may also be a plug structure. Specifically, an openingis provided at the highest point of the second pipeline 5, and a plug isprovided at the opening. When water inflows from the water supply valve1, the opening is closed by the plug, and when the water supply valve 1is closed, the plug is removed and the opening communicates with theatmosphere, so that the water in the water delivery channel 21 and thefirst pipeline 4 is sprayed from the outlet of the atomization generator3. Those skilled in the art may flexibly set the specific structure ofthe one-way check structure in practical applications, as long as theone-way check structure can be isolated from the atmosphere when thewater supply valve 1 is opened and can communicate with the atmospherewhen the water supply valve 1 is closed. In the present disclosure, whenthe water supply valve 1 is closed, a part of the water in the waterdelivery channel 21 enters the first pipeline 4 and the other part ofthe water enters the second pipeline 5. The first pipeline 4 and thesecond pipeline 5 may be connected to the water delivery channel 21through the same water outlet end of the water delivery channel 21, ormay also be connected to the water delivery channel 21 through differentwater outlet ends of the water delivery channel 21 respectively. Suchchanges to the structure do not deviate from the technical solution ofthe present disclosure, and should be defined within the scope ofprotection of the present disclosure.

It should be noted that by using the one-way check structure, thepresent disclosure enables the atomization generator to smoothlygenerate atomized water droplets. This is because when the water supplyvalve is always open, it is very difficult for the atomization generatorto form atomized water droplets under the action of water pressure.Therefore, the water supply valve can be opened to accumulate water inthe water delivery channel, and then the water supply valve can beclosed. At this time, the water in the water delivery channel and thefirst pipeline can be sprayed onto the clothing in the form of atomizedwater droplets from the atomization generator according to the principleof atmospheric communication, so as to ensure that the atomizationgenerator can perform atomized air washing of the clothing.

In addition, it should also be noted that the clothing treatmentapparatus of the present disclosure may be a drum washing machine, apulsator washing machine, a washing-drying integrated machine, aclothing care machine, etc., and those skilled in the art may flexiblyset the application objects of the technical solutions of the presentdisclosure. Such adjustments and changes to the application objects donot deviate from the principle of the present disclosure, and should bedefined within the scope of protection of the present disclosure. Thetechnical solutions of the present disclosure will be further explainedbelow in conjunction with a drum washing machine.

Specifically, the drum washing machine of the present disclosureincludes a cabinet, a drum arranged in the cabinet, and a window gasketconnected between an outer cylinder of the drum and the cabinet. Theatomization generator is preferably arranged on the window gasket, andan outlet of the atomization generator is obliquely arranged facing aninner cavity of the drum (of course, other directions of arrangement arealso possible). Alternatively, the atomization generator may also beprovided on the outer cylinder of the drum, as long as it can sprayatomized water droplets onto the clothing in an inner cylinder of thedrum to perform atomized air washing. In addition, the drum washingmachine also includes a dispensing device arranged on the cabinet. Thedispensing device includes a clothing treatment agent dispensing cavityand a water box arranged on a top of the clothing treatment agentdispensing cavity. The water delivery channel is formed in the water box(that is, the clothing treatment agent dispensing cavity is arrangedbelow the water delivery channel). A water inlet end of the waterdelivery channel is connected to the water supply valve arranged outsideof the dispensing device, a water outlet end of the water deliverychannel is connected to the atomization generator through the firstpipeline, and the water outlet end of the water delivery channel is alsodirectly connected to the outer cylinder of the drum through the secondpipeline. The one-way check valve is provided on the second pipeline.The water outlet end of the water delivery channel may be directlyconnected to the atomization generator through the first pipeline, and awater tank may also be arranged between the water delivery channel andthe atomization generator; that is, the water outlet end of the waterdelivery channel is first connected to the water tank through apipeline, and then the water tank is connected to the atomizationgenerator through another pipeline. The water tank has a function ofaccumulating water.

Preferably, the position where the one-way check valve is arranged is ata different height from the position where the outlet of the atomizationgenerator is arranged, that is, when the one-way check valvecommunicates with the atmosphere, a certain liquid level difference canbe formed between the one-way check valve and the outlet of theatomization generator, so that the water accumulated in the waterdelivery channel and the first pipeline can be sprayed onto the clothingmore easily in the form of atomized water droplets through theatomization generator. Since the position where the dispensing device isarranged is generally higher than the position where the drum isarranged in the drum washing machine, it is more preferable to set theposition where the one-way check valve is arranged to be higher than theposition where the outlet of the atomization generator is arranged,thereby making full use of the original structure of the drum washingmachine.

Hitherto, the technical solutions of the present disclosure have beendescribed in conjunction with the preferred embodiments shown in theaccompanying drawings, but it is easily understood by those skilled inthe art that the scope of protection of the present disclosure isobviously not limited to these specific embodiments. Without departingfrom the principles of the present disclosure, those skilled in the artcan make equivalent changes or replacements to relevant technicalfeatures, and all the technical solutions after these changes orreplacements will fall within the scope of protection of the presentdisclosure.
